Помогите прошу решить задачи

Answer 1

10

$y' = ( {x}^{ - 1.6 } )' = - 1.6 {x}^{ - 2.6} = - \frac{8}{5 {x}^{2.6} }$

11

$y' = ( {x}^{ \frac{2}{3} } )' = \frac{2}{3} {x}^{ - \frac{1}{3} } = \frac{2}{3 \sqrt[3]{x} }$

12

$y '= ( {x}^{ - \frac{2}{3} } )' = - \frac{2}{3} {x}^{ - \frac{5}{3} } = - \frac{2}{3x \sqrt[3]{ {x}^{2} } }$
